I was the first member here to call upon the Magnaflow numbers as been misleading and even posted what should be the actual numbers. I posted 267 to 272 BHP which translates into what RPI is saying and showing. Those numbers are 6 - 8 WHP period that is it, until the GXP can be tune.
I caught a bit flak from the members and have actually stayed away from all these discussions until now.
Whitout the ECM tune, the output of this engine will not exceed the internal parameters.
Last post on the subject.
